High Court finds Malcolm Roberts was a UK citizen

THE High Court has ruled One Nation's Malcolm Roberts was a dual British and Australian citizen at the time he was nominated for election, AAP reports.

Justice Patrick Keane on Friday afternoon ruled Senator Roberts, who believed he had renounced his British citizenship before last year's election, was a citizen of the UK at the time of his nomination.

Born to an Australian mother and Welsh father in India in 1955, the Queensland senator is one of seven parliamentarians to have their future considered by the High Court, because the constitution bans dual citizens from sitting in parliament.
